Design and build 50 MH, pilotless aircraft; to control up to 8 million [m], ten-passenger Gavin Hawks
[GH] to fly over most countries and larger islands of all six Continents day and night.

Forward Planning: The estimate of 250 MH (costing $3.472 billion [b] to cover the entire World 24/7), with a team of three (for
each of the 84 regions) with one in the air at 24/7. That was based
on six FF powered MH, improving the remaining 244 MH with hydrogen cell
fuel [HFc], doubling the cost, to $6.832b but avoiding CO2pollution, after the first six MH, two MH in the air at 24/7 over the two regions in the UK. Landing
and refueling would be required after each in 15 hours.

If
nuclear power [NP] were provided instead of HFc, refueling could be
extended to two months, on average, the team reduced to 1.05/region,
with 50 MHs, 48 MHs in the air 24/7. If the cost/MH were tripled from
$14million [m]/MH to $42m/MH, but reduced from 244 to 44 additional MHs, the cost
would be only $2.083b, saving $1.389b.)

Note: The figure of 50 MH is based on six FF MH (using fossil fuel [FF], as existing Global Hawks do). In this case, three MHs are required for each region (eg two regions are necessary for the United Kingdom, thus six MHs). Plus 1.05 nuclear fueled MHs [MHns],
MHns are required for each additional region, because very little time
for refueling and a small time is allowed for maintenance and repair,
therefore onlyan additional44 MHns are necessary.
